Our Photo Grey/Brown Blue Cut UV420 Invisible Bifocal lenses — available in Round Top (R-Top) or Flat Top (D-Shape) segment options. These bifocals provide distinct visual zones for near and distance vision within one lens, designed to help users effortlessly switch focus for reading, driving, or general tasks. The invisible bifocal design integrates a subtle segment line that remains discreet while delivering precise near-vision support without compromising aesthetics.
Enhanced with Photochromic technology, these lenses adapt to changing light conditions — transitioning from clear indoors to tinted outdoors — while the Blue Cut UV420 filter blocks blue light and harmful UV radiation, reducing eye strain and protecting visual health. Choose from UC, HC, HMC, or SHMC surface treatments to meet your specific lifestyle demands, from basic durability to premium anti-reflective and hydrophobic properties.
